Part, it is an abstract model, covers all main objects being usually directed in electric power enterprise operation.It is a kind of by providing
The standard method of power system resource is indicated with object class and attribute and the relationship between them, it is different that CIM facilitates realization
Integrated, the collection between the complete EMS system of multiple stand-alone developments of Energy Management System (EMS) application of seller's stand-alone development
At and EMS system and other be related to Operation of Electric Systems different aspect system.By defining a kind of public affairs based on CIM
Language (i.e. syntax and semantics) altogether so that these applications or system can access public number independent of the content representation of information
According to exchange information.
